SMP

under construction:Undocumented Class

The SMP has not been documented. The content contained on this page includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

Input Parameters

  • fullFalseSet to true if you want the full set of couplings. Simply for convenience so you don't have to set every off_diag_row and off_diag_column combination.

    Default:False

    C++ Type:bool

    Options:

    Description:Set to true if you want the full set of couplings. Simply for convenience so you don't have to set every off_diag_row and off_diag_column combination.

  • off_diag_columnThe off diagonal column you want to add into the matrix, it will be associated with an off diagonal row from the same position in off_diag_row.

    C++ Type:std::vector

    Options:

    Description:The off diagonal column you want to add into the matrix, it will be associated with an off diagonal row from the same position in off_diag_row.

  • coupled_groupsList multiple space separated groups of comma separated variables. Off-diagonal jacobians will be generated for all pairs within a group.

    Options:

    Description:List multiple space separated groups of comma separated variables. Off-diagonal jacobians will be generated for all pairs within a group.
